Definitions
- the present invention relates generally to lifting and securing devices. More particularly, the present invention relates to the field of vacuum valve systems used to secure and lift objects.
- Clamps may be used to hold objects securely in place.
- the extra time and effort in placing and securing the clamps is also inefficient in a manufacturing process.
- many objects have inconvenient shape or outlines that make efficient clamping difficult, if not impossible.
- Carliss An example is U.S. Pat. No. 3,219,380 issued to Carliss ("Carliss").
- Carliss uses compressed air to create a vacuum that is stored in a vacuum tank.
- the vacuum tank is in open communication with vacuum valves that are located directly over the vacuum pads.
- the vacuum valve is opened to the vacuum pads, thereby evacuating the volume within the vacuum pad and securing the detected object to the vacuum pad.
- Horton discloses a vacuum attachment that uses a vacuum pump to create a standing vacuum within a hollow frame/vacuum storage tank.
- the vacuum storage tank is connected via a hose to a sensing valve in the vacuum cup.
- the sensing valve detects an object, it opens, thereby evacuating the air contained in the vacuum cup into the vacuum.
- U.S. Pat. No. 3,322,454 issued to Mindrum
- U.S. Pat. No. 4,561,687 issued to Bostrom
- U.S. Pat. No. 5,431,469 issued to Ohno et al.
- FIG. 1 is a vacuum valve according to the present invention, the valve is in a closed position that blocks pressurized airflow;
- FIG. 2 is the vacuum valve according to the present invention, the valve is in an open position thereby allowing airflow and the creation of a vacuum within the valve body;
- FIG. 3 is the body of the vacuum valve without the sensing member
- FIG. 4 is an embodiment of the sensing member of the present invention.
- FIG. 5 illustrates an alternate embodiment of the vacuum valve according to the present invention
- FIG. 6 illustrates the turnstile chamber of the alternate embodiment of the present invention without the gear present, but with the shaft of the sensing member present;
- FIG. 7 is a top view of the turnstile according to the present invention.
- FIG. 8a is a side view of an embodiment of the turnstile of the present invention, the dashed lines show hidden lines;
- FIG. 8b is a cut-way view of FIG. 8a showing the fluid flow channels within the turnstile according to the orientation of FIG. 8a;
- FIG. 9a is another side view of the embodiment shown in FIGS. 8a and 8b, however, the view is rotated by 90 degrees relative to FIGS. 8a and 8b;
- FIG. 9b is a cut-away view of FIG. 9a showing the fluid flow channels according to the orientation of FIG. 9a.
- the present invention is a valve assembly 1 that is useful for releasably securing or holding objects.
- the valve assembly 1 senses the presence of an object to be held or secured, then, upon detection of the object, creates a vacuum on demand.
- the assembly 1 has a body 10 with a fluid inlet port 12, a fluid outlet port 14, a fluid flow channel 16 extending between the fluid inlet port 12 and the fluid outlet port 14. There is a vacuum port 18 and a low pressure channel 20 that extends between the vacuum port 18 and the fluid flow channel 16. Further, there is a sensing member receiving channel 22 that extends from the fluid flow channel 16 to the exterior of the body 10. Finally, there is a flow occlusion chamber 24 that intersects the fluid flow channel 16.
- the assembly also has a sensing member 50 with a fluid flow regulation portion 60 and a sensing portion 55.
- the sensing member 50 is adapted to be movably received by the sensing member receiving channel 22.
- the sensing member 50 is movable from a closed position to an open position.
- the fluid flow regulation portion 60 prevents, at least in part, flows of fluids through the fluid flow channel 16.
- the fluid flow channel 16 is open to the flow of fluids.
- a low-pressure condition is created within the low-pressure channel 20.
- the assembly 1 creates a vacuum-on-demand.
- one form of the sensing member 50 is a pin or rod type structure where the sensing portion 55 is located at a first end of a central shaft 62 and the fluid flow regulation portion 60, is located at a second end of the central shaft 62.
- the fluid flow regulation portion 60 is a tapered structure, tapering radially outward to a larger diameter at its distal end than that of the central shaft 62.
- the flow occlusion chamber 24 is adapted to receive closely the fluid flow regulation portion 60 and when in the closed position. This is clearly illustrated in FIG. 1.
- the sensing member 50 is biased into the closed position by a biasing structure 80 such as a spring, or the like.
- the open position of the assembly is illustrated in FIG. 2.
- the assembly 1 has the sensing member receiving channel 22 extending between the fluid flow channel 16 and the low pressure channel 20.
- the sensing member 50 when received by the sensing member channel 22, it extends through the low pressure channel 20 and extends beyond the vacuum port 18.
- the assembly 1 may include a vacuum cup 90 that is located in a position where the vacuum port is in communication with the interior of the vacuum cup 90.
- the sensing member receiving channel 22 it is within the scope of the present invention to have the sensing member receiving channel 22 extending between the fluid flow channel 20 to an exterior surface of the body 10. Therefore, the sensing member 50 may be either within or without the vacuum cup 90.
- the sensing portion 60 of the sensing member 50 is a turnchannel 64 that is adapted to work in combination with, or is rotationally attached to, the central shaft 62.
- the turnchannel 64 is a piece that includes at least a turnchannel fluid flow channel 66. Thus, the turnchannel 64 rotates between the closed and open positions.
- the turnchannel fluid flow channel 66 will further include a vacuum aperture 68 allowing fluid communication between the fluid flow channel 16 and the low pressure channel 20 through an interior vacuum channel 63 located within the central shaft 62.
- the body 10 may further includes a push-off channel 15 that extends between the flow occlusion chamber 24, which is also known as a turnchannel receiving chamber in this embodiment, and the fluid flow channel 16.
- the turnchannel 64 may further include a second push-off channel 69 that is in fluid communication with the low pressure channel of the body, said second push-off channel 69 being rotated with respect to the turnchannel flow channel 66. Then, when the turnchannel 64 is in the closed position, fluid flow is capable through the push-off channel 15 and the second push-off channel 69 and through the low-pressure channel 20 thereby creating a positive pressure, or push-off, at the vacuum port 18.
- fluid means a body whose particles move easily among themselves and is a generic term that includes liquids and gases as species.
- liquids such as water, gases such as air, and mixtures such as steam are considered fluids.
